Product description: USB-UART converter CP2104 - Polol 1308

The module based on CP2104 allows for data conversion between USB - UART standards. Using the converter, data can be exchanged between a PC equipped with a USB port and a microcontroller chip that supports a popular serial interface. Additionally, the chip has digital general purpose leads (GPIO) as goldpin connectors - 2.54 mm raster. CP2104 is compatible with popular FT232, so it can be used as programmer for Arduino.

Default operating voltage is 3.45V, however the Polol module tolerates higher values, including 5V signals. In the operating system, the adapter is seen as virtual COM port, which means it can be used with any terminal or program supporting serial standard - RS232. The manufacturer provides drivers for the systems: Windows XP, Windows Vista, Windows 7, Windows 8, Linux, and Mac OS X.

The outputs are popular goldpin connectors (2.54 mm raster), which enable connection of the sensor with wires or direct connection to the contact board.

GPIO leads

The module has four digital GPIO outputs, which can be controlled via a one-time programming ROM. For more details see documentation.

Change default operating voltage

CP2104 allows you to select the voltage with which the outputs work. The default setting is 3.45 V. To change this value to a lower one, solder the jumper at the bottom of the module. Other, lower voltage up to 1.8 V can be connected to VIO output.
